It's an interesting piece that fused glitched dynamics with an obvious dubstep-oriented sound. I like how the outro is performed in a very unobtrusive way and overall the song structure is pretty solid. I would however point out that the lead synths sound a bit cluttered at some points, with the chords creating a slight dissonance in the progression. Modulating said synths better would give a better dynamic sound and since dubstep is also partly inspired by chiptune music, try to put some vibrato and stereo enhancing to make it sound more expressive, reminiscent of that era.
The mastering is surprisingly tight and I love the drums you used. I think an atmosphere bed would have helped closing the gap in the section before the outro and more rhythmic synths in the transitions between the dubstep parts would have helped keeping things interesting and refreshing.
Nonetheless, you've done a good job
